VALVE-LOCK.

Specification of Letters Patent.

Patented Aug. '7, 1917.

Application filed 'May 4, 1916. Serial No. 95,513.

description, in connection with the accompanying drawings, is aspecication, like letters on the drawings representing like parts.

My present invention is a combined valve lock adapted specially forapplication to a lock of the Yale or safety type and a standard valve,having a T-head stem or similar arrangement, and a member adapted toconnect the turning cylinder of the lock with the valve stem. The objectof the invention is to improve and perfect this type of device, andespecially to provide an economical and simple arrangement for unit-ingsuch a lock and valve with provision for free turning movement of thelock barrel the valve is `turned to permit withdrawal of the key in thelock. It is also an object of the invention to enable such a lock to beapplied to existing types of valves, particularly those ofthe ordinaryT-stem type. A further object of the invention is to provide an efcientcover and assembling arrangement to hold the valve, valve stem, lockbarrel and intermediate connecting member in assembled position,protecting the same from disarrangements, dust, or tampering bymischievous persons.

Other details of the invention, novel combinations and advantages willbe further pointed out and claimed.

Referring to the drawings,

Figure 1 is a vertical cross sectional view of my device through thelock valve and connecting member;

Fig. 2 is a view partly in cross section at right angles to that shownin Fig. 1; and

Fig. 3 is a perspective view of a novel form of the device or connectingmember by which the barrel of the lock and the valve are operativelyconnected.

Vhile my combined lock and valve device may be advantageously employedin a variety of ways, it is of special importance in application to shutoff the gasolene supply in an automobile, thus preventing theft of thema.- chine, as well as leakage. The valve and lock may be convenientlyarranged on the dash of an auto within reach of the driver. Such a dashis indicated at 1, having a recess 2 adapted to receive the lock 3having the turning barrel a with a slot to receive the key 5, such lockbeing of the standard -Yale or similar safety type so far as theseconstructional features are concerned. I make the inner end of thebarrel 4L with a projecting portion 6, cut away at one side as indicatedat 7 and extending practically across the entire diameter of the barrelat the opposite point, as indicated at 8in Fig. 2, thus affording twosmooth faces on the projection 6 as shown at 9 and 10 which are adaptedto contact with a lug 11 carried by the member 12, as will be furtherexplained. The projecting portion 6 of *the barrel is furthermore tappedaxially to receive the correspondingly threaded shank 13 of a screw 14intended to secure a washer 15 in position to aid in holding the member12 and lock barrel together. The member 12 is formed with a bored recess16 in which the projecting lug 11 is left. A larger and inner recess 17opening through a slot 18 in the exterior of the member 12 is providedand adapted to receive the washer 15 therein, which is of sufficientdiameter to engage the slightly projecting walls between the recesses 16and 17, as clearly shown in Fig. 1. The member 12 is also bored at 19 tofacilitate the entrance and manipulation of a screwdriver to turn thescrew 14. In assembling the member 12 to the lock barrel, the same isfitted thereon, preferably over and upon the slightly reduced portion 20(seeF ig. 1), the washer 15 is slid through the opening 18 into theinner enlarged recess 17 and the screw 14 fitted through the boredopening 19 and through said washer, and threaded into the tapped recessin the end 6 of the lock barrel. As thus assembled,h rotation of thelock barrel 4: through manipulation of the key 5, will rotate saidbarrel until one of the faces 9 or 10 of the end projection 6 strikesagainst the lug 11, whereupon the further rotative movement of the lockbarrel 4 will turn the member 12 with said barrel. To adapt the member12 to turn on or off a valve I cut a slot 21 therein which is adapted toiit over the T-head 22 of a valve stem 23 i in a valve 21 of the usualtype, to which are IIJ valve is turned oif by a quarter rotation, theconstruction above described permits a reverse rotative movement of thelock barrel il: is thus provided for sufficient to rotate the entirebarrel into proper position so that the keyl 5 can be withdrawn. This isa feature of special importance in this type of look and necessitatesthe provision of means to accomplish such withdrawal of the keyirrespective of the position in which the T-head 22 and member 12 may beleft. The formation of the projection 6 on the lock barrel with the freespace 7 therein effects the purpose desired by permitting` saidprojection to be turned entirely around when one face 10 is bearingagainst the lug 11 until the other face 9 may bear against saidprojection 11 and move the member 12 and valve in a reversedirection'from that iirst described.

In order to hold the valve and lock in assembled and protected position,I provide a cover 27, preferably of metal, having a flange 28 formedthereon, which is secured to the inside of a dash 1 by screws 29, orother suitable means. A filling member 30 of wood, porcelain, or anysuitable material,

is adaptedto iit solidly within the cover 27 and having a bored recessof appropriate diameter to receive `the member 12 and T- head 22 andpermit rotation thereof, is also provided, if necessary.

A further feature of the cover 27, in addr tion to the protectionafforded to the device and the holdingof the valve and turning member inassembled relation, is that it acts asfabrace or support for the pipino25 and 26. As hereinshown in Fig. 1, the valve 24 is fitted closelywithin the cover 27 and the threaded ends 25`and 26 of the connectingpiping are positioned through suitable holes in the cover 27 unitingboth cover, valve and pipes rigidly. This aifords a strong, bracedconstruction, and eliminates vibration and further holds the valve inproper position.

The operation of my lock and valve has already been described, and theassembling of the same `with the cover 27, can be easily and quicklyeffected, such cover constituting both a holder for the valve 24 and ameans to retain the lhead 22 into the slot 21 of the turning member 12.The `cover also prevents any meddling with the valve or turning of thesame excepting through the manipulation of the lock 3 and key 5.Therefore, when the owner of a car equipped with this apparatus turnsoff the supply of fuel, and withdraws the key 5, he is reasonablyassured that no one willy be able to start the car without the keytherefor.

My invention is further described and deined in the form of a claim-asfollows:

In a device of the kind described, the combination of a lock, a l'headvalve, and an intermediate member` operatively connecting said lock andthe T-hea'd of said'valve, said member having a recess in one end toengage the T-head4 of the valve, arecess in the opposite end and alugtherein adapted to be engaged bythe turning movement ofthe lockbarrel, and an inclosing cover coinprising means to'hold said member,valve, and lock in operative position.

In testimony whereof, I have signed my name to'this specification, inAthe presence of twosubscribing witnesses.
